Anti erk

Manufactured by Bioworld Technology
Sourced in United States, China

Anti-ERK is a laboratory reagent used in biological research. It is a monoclonal antibody that specifically binds to the extracellular signal-regulated kinase (ERK) protein, which is a key component of the MAPK signaling pathway. Anti-ERK can be used in various research applications, such as Western blotting, immunoprecipitation, and immunohistochemistry, to detect and quantify ERK expression and activation.

Western Blot Analysis of Spinal Cord Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Spinal cords were homogenized with a micro content motor-operated tissue homogenizer (Kimble Kontes, USA), using protein extraction kit (Sigma, USA) supplemented with a cocktail of protease inhibitors. The homogenates were centrifuged at 13,000g for 20 min at 4 ℃, and the supernatants were collected. The protein concentration was determined by BCA method. Equal amounts of protein (30 μg) were separated by SDS-PAGE and electroblotted onto PVDF membrane (Immobilon-P, Millipore, USA). After non-specific binding was blocked with 5% non-fat dry milk, membranes were incubated at 4 ℃ overnight with anti-MBP, anti-Akt, anti-ERK, anti-JNK, anti-P-Akt, anti-P-ERK, anti-P-JNK and anti-β-actin (1:1000, Bioworld, USA). After washing the membrane the next day, it should be incubated with the second antibody at room temperature for 2 hours. Bands were visualized with an enhanced chemiluminescence (ECL) system (GE Healthcare Life Sciences, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
